> This patch fixes a problem where the NVMUpdate Tool, when using the PHY
> NVM feature, gets bad data from the PHY because of contention on the
> MDIO interface from get phy capability calls from the driver during regular
> operations.  The problem is fixed by adding a check if media is available
> before calling get phy capability function because that bit is not set when
> device is in PHY interaction mode.
